Background
Cloud storage is one of the most cost-effective, secure and scalable ways for companies to store their data in third-party datacenters through a cloud service provider. Thanks to rapid development of processing and storage technologies, many organizations are rapidly shifting more core business to cloud platforms. However, many organizations still struggle with a concern: is data safe in the cloud?
The obstacles concerning cloud security are somewhat complex, but they can be divided into two broad categories:

- Security concerns faced by cloud providers (organizations providing software-, platform-, or infrastructure-as-a-service via the cloud)
- Security concerns faced by their customers (companies or organizations who host applications or store data on the cloud)
Why are people concerned with cloud security?
There is a great deal of uncertainty revolving around the idea of cloud security which is proving to be a significant barrier to adoption. To a certain extent, this paranoia is understandable. The idea of storing your sensitive business data on servers and systems that you don’t have control over is intimidating. Understanding all these concerns, cloud companies are continuously working to create a range of security options that make sure that the data is encrypted and safely stored.
With cloud computing gaining strong ground, the concerns related to cloud security have become more relevant. The problems have become more complex as no two clouds are the same or serve the same purpose. Depending on their need, enterprises can choose from different types of cloud computing services like IaaS, PaaS and SaaS. Every type of cloud computing platform presents its unique set of challenges and security concerns.
Cloud storage providers and enterprises share a collective responsibility to ensure that your data is encrypted and safely stored. Implementation of baseline protection of the platform begins at the end of cloud storage providers. It further includes ensuring protection to the data they process, by methods such as authentication, access control, and encryption. To ensure further protection, many enterprises strengthen these protections with additional security measures. These security measures help in strengthening cloud data protection and in ensuring the right access to sensitive information in the cloud.
Cloud storage risks
Cloud security is tight, but it’s not infallible. By using automation and brute force attacks, hackers can get access to the files stored in the cloud. That said, one of the biggest risks with respect to storing data in the cloud is privacy. Even if this data is not stolen, it still can be viewed or accessed. Law enforcement agencies or government departments can request for access to information stored in the cloud. Depending on the nature of the request, cloud service providers can provide or deny access. As data revealed by large companies like Google and Microsoft show, every year, there are a huge number of requests from governments for providing access to information.
Cloud security controls
Cloud security controls are created to protect the systems against any weaknesses, and minimize the possibility of an attack. Cloud security controls can be classified into the following categories:
Deterrent controls
As the word implies, deterrent controls are created to minimize the possibility of attacks on a cloud-based system. Similar to a stop sign on a road or a warning sign placed on a property, a deterrent control minimizes the threat level by warning potential hackers that there will be legal consequences if they proceed to carry out any illegal action.
Preventive controls
Detective controls
Detective controls are meant to take action based on any incidents or events that take place. For example, in the case of an attack, a detective control will alert the security team or a system on the likelihood of an intrusion, and the steps that must be immediately taken. Intrusion detection systems and network monitoring tools are actively used by enterprises to identify and recognize that take place on cloud-based systems.
Corrective controls
Corrective controls are intended to minimize the impact of an attack. Restoring backups automatically or isolating a compromised system are examples of corrective controls.
How cloud enterprises protect my data?
To ensure safety of data in the cloud, there are several methods and techniques. Some of these methods are described below:
Cloud data encryption
To keep data safe and secure, the first line of defense for a cloud-based platform is encryption. By default, encryption techniques use a mix of complex algorithms to protect information stored in the cloud. To view encrypted files, the attackers will need access to an encryption key. While encrypted information can also be viewed, the process to decrypt requires not only a huge amount of time, but also significant computing resources.
AI tools and auto-patching
AI can be a great asset for ensuring the enterprise security posture of a company. AI can be used to analyze huge volumes of network traffic and identify malicious activity with great speed and accuracy. AI can also be used for understanding attack patterns and prevent future attacks from happening. Auto-patching enables enterprises to completely automate their patch management process. This includes scanning all virtual machines to detect and fix the missing patches and ensure compliance to security.
Built-in firewalls
A firewall is a security product whose function is to stop malicious traffic. In the context of the cloud, a cloud firewall is a firewall that is hosted in the cloud and provides a virtual barrier and protection around cloud-based assets.
Third-party security testing
While finalizing a cloud provider ensure that they have in place third-party security companies to test and certify their servers and software. The outside monitoring decreases the chances of attack by hackers and cybercriminals. Third-party security testing also allows cloud service providers to address possible vulnerabilities before any hackers get an opportunity to exploit them.
What are the steps that I can take to keep my cloud data safe?
Nothing is 100% secure when it comes to the Internet. That is why it is essential that you incorporate all necessary steps to keep your cloud data safe. Here are some of the key steps you can take to tackle the issue of data theft:
Organization-wide security policies
Always backup your data
Cloud storage is by design built to protect enterprises from different attacks and natural disasters.
Consistent security updates
Your system frequently alerts you for and reminds you about various updates. All these updates come with tools to make your network more secure and provide protection against threats. Cloud service providers, server providers and organizations must consistently update their security measures.
Regulatory compliance
When you select a cloud computing service provider, ensure that the service provider follows the laws as enforced by the respective governing authorities in specific regions. You can also check the credentials of the service provider with respect to industry-specific regulatory compliance such as HIPAA (For the Healthcare industry) or PCI Security Council Standards (For any merchant accepting credit cards). Regulatory Compliance for applications, infrastructure and services provided by the cloud computing service provider must be thoroughly checked before any transition to the cloud.
Trust, but verify
You have to validate the faith you put in your cloud computing service provider. Trust is absolutely vital because everyone must have access to your cloud-based infrastructure. But it’s essential that you also monitor and audit continuously so you can verify business-critical activity and manage risk effectively.
Final thoughts
No system is 100% safe, but cloud infrastructure almost reaches this goal. Data is safe in the cloud, but some precautions have to be in place to ensure everything works smoothly. It is also equally important to adhere to regulatory and compliance requirements as mandated by the law.
